Crystals Procurement Notes

Verify the specific suffix (e.g., DG) against the manufacturer's official datasheet to confirm exact specifications such as packaging type and compliance status. Ensure the requested part matches the required frequency, load capacitance, and package dimensions for your design.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required in a compact 3225 footprint. Consider the 50 ppm tolerance and -20°C to +70°C temperature range against system requirements. Verify compatibility with the target circuit's load capacitance and drive level constraints.

Crystals Part Context

This part belongs to the MX3 series of quartz crystals from Meritek Electronics Corporation. The series offers various frequencies and packages for general-purpose timing applications. The MX3KJJC38M4 specifically addresses needs for moderate precision timing in consumer and industrial electronics.

Crystals Replacement Considerations

Check for direct substitutes with identical 38.4 MHz frequency, 22 pF load capacitance, and 3225 package size. Verify that alternative parts meet or exceed the 50 ppm tolerance and 3 ppm/year aging specifications.
